Cooperation-based resource allocation method in heterogeneous fusion network

Abstract

The invention provides a cooperation-based resource allocation method in a heterogeneous fusion network, which mainly solves the problem that resources of a traditional heterogeneous network cannot be fully utilized. The cooperation-based resource allocation method in the heterogeneous fusion network comprises the following implementation steps of: 1-, in the heterogeneous fusion network which consists of a network A and a network B, if the network A has resources directly accessed to a core network, applying resources from the network A by the network B and accessing the resources applied from the network A to the core network; 2-, sending a communication request to an access point a of the network A by an access point b of the network B and an authorized user of the network A to apply the resources; 3-, allocating the resources for the access point b of the network B by the access point a of the network A and transmitting the resources, and when the access point a of the network A cannot meet the requirement of the authorized user of the network A, enabling the authorized user of the network A to seek the cooperative transmission of the network B; and 4-, sending own data to the access point b of the network B by the authorized user of the network A of seeking cooperation, and after the data of a user of the network B and the data of the authorized user of the network A are fused by the access point b, applying the resources from the access point a of the network A to complete transmission. The cooperation-based resource allocation method in the heterogeneous fusion network can be used for optimizing the throughput of the heterogeneous fusion network.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a resource allocation method in a heterogeneous network, which can be used in the process of optimizing the throughput of the heterogeneous network. Background technique [0002] Wireless communication technology has developed rapidly in recent years, and wireless communication systems emerge in an endless stream to provide users with a heterogeneous network environment, including wireless personal area network Bluetooth, wireless local area network, such as Wi-Fi, wireless metropolitan area network WiMAX, public mobile communication Networks such as 2G, 3G, satellite networks, Ad Hoc networks, wireless sensor networks, etc. Although these wireless networks provide users with a variety of communication methods, access methods and ubiquitous access services, they greatly facilitate people's lives. However, the diversified network puts forward higher requirements on the rati...

Problems solved by technology

For example, in a cognitive network based on collaboration, on the one hand, authorized users will have priority to obtain the right to use resources. When there are surplus resources in the network, cognitive users can use these remaining resources for their own communication, so that resources However, this kind of utilization cannot be fully guaranteed. Once the authorized user has a demand, the cognitive user must release these resources, and sometimes even cause call drop; on the other hand, when the channel condition of the authorized user deteriorates, the Seek the cooperative transmission of cognitive users, and give the cognitive users the right to use their own resources. Under this condition, the authorized users who cannot communicate at all can complete the communication task, but this is very unfriendly to the cognitive users who participate in the collaboration, and the cognitive users hardly get any benefits, which will not only increase the complexity of their own equipment and algorithms, but also consumes a lot of power
